I have an M510 and I love it but it needs to be taken apart and cleaned every year or so. It accumulates an insane amount of crap inside it which if left unchecked will eventually lead you to think there's a software issue or wireless interference as your pages scroll up and down randomly by themselves.

Most people probably just replace mice once they start acting up because they either don't want to bother cleaning it or else don't realise it can be taken apart and cleaned easily which fixes 99% of mice issues.
